The AI Fix #73: Gemini gambling, poisoning LLMs and fallout

🧠 In episode 73 of The AI Fix, hosts Graham Cluley and Mark Stockley explore a sweep of recent AI developments, from the rise of AI-generated content to high-profile figures relying on chatbots. They discuss research suggesting Google Gemini exhibits behaviours resembling pathological gambling and report on a Gemma-style model uncovering a potential cancer therapy pathway. The show also highlights legal and security concerns— including a lawyer criticised for repeated AI use, generals consulting chatbots, and techniques for poisoning LLMs with only a few malicious samples.

Microsoft: 100 Trillion Signals Daily as AI Fuels Risk

🛡️ The Microsoft Digital Defense Report 2025 reveals Microsoft systems analyze more than 100 trillion security signals every day and warns that AI now underpins both defense and attack. The report describes adversaries using generative AI to automate phishing, scale social engineering and discover vulnerabilities faster, while autonomous malware adapts tactics in real time. Identity compromise is the leading vector—phishing and social engineering caused 28% of breaches—and although MFA blocks over 99% of unauthorized access attempts, adoption remains uneven. Microsoft urges board-level attention, phishing-resistant MFA, cloud workload mapping and monitoring, intelligence sharing and immediate AI and quantum risk planning.

MAESTRO Framework: Securing Generative and Agentic AI

🔒 MAESTRO, introduced by the Cloud Security Alliance in 2025, is a layered framework to secure generative and agentic AI in regulated environments such as banking. It defines seven interdependent layers—from Foundation Models to the Agent Ecosystem—and prescribes minimum viable controls, operational responsibilities and observability practices to mitigate systemic risks. MAESTRO is intended to complement existing standards like MITRE, OWASP, NIST and ISO while focusing on outcomes and cross-agent interactions.

Google won’t fix new ASCII smuggling attack in Gemini

⚠️ Google has declined to patch a new ASCII smuggling vulnerability in Gemini, a technique that embeds invisible Unicode Tags characters to hide instructions from users while still being processed by LLMs. Researcher Viktor Markopoulos of FireTail demonstrated hidden payloads delivered via Calendar invites, emails, and web content that can alter model behavior, spoof identities, or extract sensitive data. Google said the issue is primarily social engineering rather than a security bug.

AI Risks Push Integrity Protection to Forefront for CISOs

🔒 CISOs must now prioritize integrity protection as AI introduces new attack surfaces such as data poisoning, prompt injection and adversarial manipulation. Shadow AI — unsanctioned use of models and services — increases risks of data leakage and insecure integrations. Defenses should combine Security by Design, governance, transparency and compliance (e.g., GDPR, EU AI Act) to detect poisoned data and prevent model drift.

Hidden Cybersecurity Risks of Deploying Generative AI

⚠️ Organizations eager to deploy generative AI often underestimate the cybersecurity risks, from AI-driven phishing to model manipulation and deepfakes. The article, sponsored by Acronis, warns that many firms—especially smaller businesses—lack processes to assess AI security before deployment. It urges embedding security into development pipelines, continuous model validation, and unified defenses across endpoints, cloud and AI workloads.
